THREADER AND CUTTER.

Speccaton of Letters Patent.

Patented Feb. 6, 1906.l

Application filed November 6, 1903. Serial No. 180,021.

T0 all whom, t may con/cern.- i

t Be 1t known that I, WILLIAM C. GRIFFIN, a citizen of the United States, and a resident of Verdigris, in the county of Knox and State of VtiQn, preferably a drop-forging, and presenting 1n one piece the fixed jaw of the wrench, besides a handle, and the inner vertical walls and upper and lower horizontal members of laterally-disposed stocks for the cutter and 'threader, respectively, suitable cutting and threading dies', `of steel, being secured in the stocks, together with die-adjusting provision, whereby either the cutter or threader may be quickly arranged for the reception of a tube or rod of one of several sizes and the same conveniently severed or threaded, as the case may be.

There are other important features connected with the invention which in addition to those alluded to are clearly set forth in the subsequent detailed description.

In the accompanying drawings, forming part of this specification, Figure l is an elevational view of the improved tool. Fig. 2 is a vertical section on the broken line 2 2, Fig. l, and showing more particularly one of the cutting-dies. Fig, 3 is a similar view on the line 3 3, Fig. 1, and illustrating more especially one of the threading-dies.'

Similar reference characters are employed. to designate corresponding parts throughout the several -figures wherein they occur.

The main or body portion, which, as before intimated, is in the form of a drop-forg ing, presents in a single piece the upper stationary` j aw A of the pipe-wrench, the lower handle B, and intermediately-located and laterally-'extended upper and lowerliorizontal members C C and D D of the cutter and threader stocks.

Pivotally attached to the main or body portion contiguous to the jaw A is a hookjaw A generally of the configuration indicated in Fig. l and embodying integrally the lower inclined part e, merging in the vertical portion a and concluding with the upper horizontal terminal a2, extending toward and adapted under some conditions to overhang the extremity of the jaw A. The contiguous edge faces of tho jaws A A are provided. with transverse serrations in order to provide the required biting capacity for the jaws. The serrated face ai* of the stationary jaw is beveled or .inclined in order to appropriately cooperate with the pivotal jaw in securing the cam-like grasping effect of the latter.

As the arrangement and operation of both the cutter and threading stocks are substantially alike, with the exception that the working faces of the dies in one .instance are equipped with cutting-ribs c, while the dies in the threading-stock having threading-ribs d, a description of one of these stocks and parts coactive therewith will serve for an understanding of both.

The horizontal members C C are longitudinally grooved in their opposite faces, as indicated by dotted lines c in Fig. 1 and in full lines, Fig. 2. In these grooves and slidingly engaged are the upper and lower lugs c2 c3 of the inner and outer companion dies C2 C3, the grooves extending only sufficiently far to permit the back of the die to bear against the inner end wall of the stock-opening, which wall is presented by the contiguous edge of' the main or body portion. The die C3 is retained in position after being seated by a cotter-pin C4, insertible in both members C C and intermediate part of the die C3.

A vertical. section C5 connects the members C C/ at their outer ends through the medium of machine-screws c4, said. section having a centrally-located threaded perforation in which bears the threaded shank e of a screw or bolt E, the inner extremity of Athe shank bearing against the back of the movable die C2 for forcing it in the direction of its companion and retaining it against recession.

From the description thus far it will be appreciated that When required the tool may be used as a pipe or rod wrench, the pivotal jaw being caused to take over the pipe or rod and the tool oscillated in a manner and for a purpose obvious to those familiar with such wrenches.

When it is desired to either sever or thread a tube or rod, the latter is introduced into position in one or the other of the stocks and the movable die thereof properly adjusted.

I prefer that the dies shall be of hardened steel. The employment of the cotter-pins IOO TIO

permits companion pairs of dies to be superceded by another pair the working Afaces of which will be differently conditioned-as, for instance, having a thread of a different pitch or degree of coarseness-or shaped to serve as a nut or tap wrench.

The improved tool is comparatively simple and inexpensive, extremely useful, and highly durable.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is*- A device of the character described, comprising a handle provided with integral laterally-extending fixed members, each having a longitudinal groove in its inner 'face and a transverse hole, inner and outer dies havingI ber, A.
